> 2) fuel consumption: at supersonic speeds, they suck gas like it's going out of style.

Not as much as you'd think, the Concorde supercruised at Mach 2 without the burners, and in the cruise the Olympus engines were astonishingly efficient even by modern standards.

Take off, climb out, sub-sonic and transonic flight was the real fuel slurper with the Concorde.

Submission + - Graphene Light Bulb Coming To Stores Soon->

An anonymous reader writes: A light bulb made from graphene — said by its UK developers to be the first commercially viable consumer product using the super-strong carbon — is to go on sale later this year. The dimmable LED bulb with a graphene-coated filament was designed at Manchester University, where the material was discovered in 2004. It is said to cut energy use by 10% and last longer owing to its conductivity. It is expected to be priced lower than current LED bulbs, which cost about £15 each.

I disagree. The problem is that there is there is no LCD monitor that does everything competently. $1500+ professional color-accurate monitors may be good for photoshop but are lousy for anything with moving images.

Want a good LCD for gaming? There are TN panels that will refresh at 144Hz with fast response times. The tradeoff is very poor color reproduction and narrow viewing angles.

An IPS panel will give better colors and viewing angles at the expense of low refresh (few go over 60Hz), and 'IPS glow' is a real problem with them.

Then there is the panel lottery you have to play when you buy them. Many vendors and manufacturers have a threshold for the number of dead/stuck pixels that are deemed acceptable. Backlight bleed and uniformity can vary widely between different monitors of the same make and model.

CRTs had issues with their bulk, limited size and power consumption but LCD have introduced a whole world of new problems.

Perhaps our only hope is more affordable and reliable OLED displays.

I'm using a CRT monitor right now, a 21" IBM P275 with a Trinitron tube. Right now I'm enjoying near perfect color reproduction, blacks that are actually black, zero input lag, no ghosting, nothing that resembles backlight bleed and no stuck/dead pixels. Haven't noticed flyback whine for years but that's probably down to my age. LCD is still inferior to CRT in many ways and you have to wonder what CRTs we would have today if development had continued. LCD has also taken a step backwards recently with the introduction of LED backlights, they make for thinner panels and lower power consumption but uniformity of many recent panels is really poor.

Having said that, my CRT will probably have to go this year, most probably late in the spring when the heat the thing generates is no longer welcome. My desk is also sagging from the weight of it sitting there for nine years.
